+There is however a catch. The keyword scanners in \LUAMETATEX\ are implemented
+slightly different. When \TEX\ scans a keyword it will (case insensitive) scan
+for a whole keyword. So, it scans for \type {height} and when it doesn't find it
+it will scan for \type {depth} etc. When it does find a keyword in this case it
+expects a dimension next. When that criterium is not met it will issue an error
+message.
+
+In order to avoid look ahead failures like that it is recommended to end the
+specification with \type {\relax}. A glue specification is an other example where
+a \type {\relax} makes sense when look ahead issues are expected and actually
+there in traditional scanning the order of keywords can also matter. In any case,
+when no valid keyword is seen the characters scanned so far are pushed back in
+the input.
+
+The main reason for using an adapted scanner is that we always permit repetition
+(consistency) and accept an arbitrary order. Because we have more keywords to
+process the scanner quits at a partial failure. This prevents some push back and
+also gives an earlier warning. Interesting is that some \CONTEXT\ users ran into
+error messages due to a missing \type {\relax} and found out that their style has
+a potential flaw with respect to look ahead. One can be lucky for years.
+
+Back to rules, there are some extra keywords, two deal with an offset, and four
+provide margins. The margins are a bit special because \type {left} and \type
+{top} are the same as are \type {right} and \type {bottom}. They influence the
+edges and these depend on it being a horizontal or vertical rule.
